Description
Technical field
The utility model relates to a kind of termination.
Background technology
At present, when locomotive electric cad system overhaul of the equipments or electrical equipment malfunction, sometimes need to change electric equipment, need the wiring of electric equipment to remove, very large inconvenience can be brought to inspection and maintenance like this.Meanwhile, when the small area analysis power consumption equipment of the voltages such as many places needs wiring, be generally transferred by a terminal board or connector, but terminal board and connector need to take a large amount of spaces, Costco Wholesale is also very high.
How to solve the problems of the technologies described above and become this those skilled in the art's problem demanding prompt solution.
Utility model content
The purpose of this utility model is just to provide a kind of locomotive electric cad system equipment wiring switching device, difficulty of taking out stitches when solving prior art maintenance of electrical equipment and safeguard, employing terminal board and the technical problem that connector takes up room greatly, cost is high.
The purpose of this utility model is realized by following technical proposals:
A kind of locomotive electric cad system equipment wiring switching device, comprise shell, shell offers a socket mouth, corresponding socket is fixed with shell fragment and conductive plate in the enclosure, shell fragment is fixed on outer casing inner wall, one side pressure is on conductive plate, the passage stretched into for wire is had between bottom conductive plate and outer casing inner wall, shell can have briquetting in top, one end of briquetting and housing hinge, when briquetting upwards turn in the process of vertical state, briquetting bottom applies downward pressure to shell fragment, makes the pressure of shell fragment end alleviation to conductive plate.
As preferably, described shell is by upper shell and lower house is detachable connects and composes.
As preferably, each socket described is a corresponding briquetting all separately.
Compared with prior art, the beneficial effects of the utility model are: adopt this wiring switching device to not only simplify the wiring of electric equipment, and the difficulty of taking out stitches when solving maintenance of electrical equipment and safeguard.This wiring switching device structure is simple, reasonable in design, cost is low, and installing space is little, be specially adapted to the wiring of the small area analysis circuit (as lighting circuit, control circuit, microcomputer signal circuit etc.) on locomotive, and need the situation simultaneously connecing several equipotential power consumption equipment.

Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
Shown in Fig. 1-5, a kind of locomotive electric cad system equipment wiring switching device, comprise the shell by upper shell 6 and lower house 7 clamping, shell offers a socket mouth 1, corresponding socket 1 is fixed with shell fragment 5 and conductive plate 4 in the enclosure, one end of shell fragment 5 is fixed on outer casing inner wall, the other end is pressed on conductive plate 4, the passage 8 stretched into for wire is had between bottom conductive plate 4 and outer casing inner wall, shell can have briquetting 2 in top, one end of briquetting 2 and housing hinge, when briquetting 2 upwards turn in the process of vertical state, briquetting 2 bottom applies downward pressure to shell fragment 5, make the pressure of shell fragment 5 end alleviation to conductive plate 4.
Described shell fragment 5 has horizontal part 501, vertical portion 502 and a kink 503, horizontal part 501 and vertical portion 502 are connected as one by kink 503, horizontal part 501 is fixed in outer casing inner wall with the link position of kink 503, horizontal part 501 is pressed on conductive plate 4, bottom, vertical portion 502 is free end, and bottom is to having a pit 9 by free end in the enclosure.The passage 8 that this free end correspondence stretches into for wire offers corresponding through hole 504.
As preferably, each socket 1 described is a corresponding briquetting 2 all separately.Can the insertion of the wire connected be needed to fix or take out each root separately like this to control.
Can make 2 holes or porous as required for the socket 1 on shell, number of cables of simultaneously can transferring as required selects the wiring switching device of corresponding hole count.
In use, briquetting 2 is upwards turn to vertical state, now briquetting 2 bottom applies downward pressure to shell fragment 5 top, make the pressure of shell fragment 5 end alleviation to conductive plate 4, then insert in the passage 8 below conductive plate 4 by wire core 3 by socket 1, downwards upset briquetting 2 to level, now shell fragment 5 recovers the pressure to conductive plate 4, thus wire core 3 is tightly pressed in conductive plate 4 times, 2 or multiple conducting wires can be connected by conductive plate 4.Again turn to by briquetting 2 vertically, wire core 3 just can easily take out from socket.
This wiring switching device not only simplify the wiring of electric equipment, and the difficulty of taking out stitches when solving maintenance of electrical equipment and safeguard.Not only structure is simple, and cost is low, and installing space is little, is specially adapted to the wiring of the small area analysis circuit (as lighting circuit, control circuit, microcomputer signal circuit etc.) on locomotive, and needs the situation simultaneously connecing several equipotential power consumption equipment.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
